Conduct Incoming material inspection as per ASME SEC II Part A, B & C and for proper Size, specification, condition, storage and free from defects or contamination. Check the available WPS have been approved and available with welders. Check the welding equipment, oven, Quivers are in good condition and calibrated as appropriate and verify their certificates as per BS 7570. Review WPS and Ensure that approved WPS are followed and prepare & witness for new WPS with PQR if essential parameters are changed as per ASME SEC IX, & AWS D1.1.Witnessing of welder Qualification Tests - witnessing the preparation of test coupons and conduct welder qualification tests as per ASME SEC IX along with client QC representative.Welder approvals - verify the availability of adequate valid welders and monitor the only approved welders as required are used in construction and update qualified welder summary list.Conduct tool box meeting to concerned welders and fabrication personnel and provide training to the new welders in different materials as per project requirements.Check welding consumables as per ASME SEC II Part C and Verify the drying, storage, exposure and conditioning of low hydrogen, non-low hydrogen, stainless steel electrodes and wires and SAW fluxes.Monitor Consumable control, storage and issuance in accordance QC Procedures.Inspection of Joint FIT-UP for correct bevel angle, root face & root gap as per ASME B31.3 / WPS.Check and verify the alignment, orientation, straightness and dimensions are as per latest revision of isometric drawings.Verify the proper pre welding distortion control by tack welds, bridge pieces, jigs etc. for good workmanship and to code ASME B31.3/ WPS.Check and verify the preheating method, location, control method and monitor the minimum preheat maintenance.Monitor the suitability of weather condition in accordance with code. Check and verify current, volts, travel speed, polarity and heat input are in accordance with WPS.Verify the purging gas type, pressure/flow rate and control method for alloy & stainless steel pipe welding and measure the level of oxygen content inside the pipe with oxygen analyzer.Conduct visual Inspection of root run and penetration. Verify inter run cleaning and check maximum inter-pass temperature adherence and its control method as per WPS.Check weld bead sequence, electrode weaving, Verify each weld is marked with correct weld no and welder symbol and check weld appearance (surface finish, toe blend, root finish) and suitable profile & cleanliness for NDT methods.Ensure all NDT is completed as per ASME SEC V and review report.Monitor PWHT for compliance with ASME B31.3 and QC procedures and check heating method & time, temperature chart (Graph).Prepare NCR for welding non conformities with recommendation and coordinate with construction for possible corrective measures.Ensure all modifications are included in the AS-BUILT drawing after checking final dimensional stability.Line check and prepare punch list & clear with concerned construction team.Preparation of final quality control reports for approval and submission to clients.
